CaO-Al<SUB>2</SUB>O<SUB>3</SUB>-SiO<SUB>2</SUB>=50-42-8 wt% eutectic slags, similar in composition to a secondary steelmaking slag, containing different amounts of CaS, were heated between 1673-1873 K. DTA was performed. Samples were characterized by EMP and XRD. Four main phases were present: CaO·Al<SUB>2</SUB>O<SUB>3</SUB>, 2CaO·Al<SUB>2</SUB>O<SUB>3</SUB>·SiO<SUB>2</SUB>, 2CaO·SiO<SUB>2</SUB> and 23CaO·14Al<SUB>2</SUB>O<SUB>3</SUB>·CaS or 22CaO·14Al<SUB>2</SUB>O<SUB>3</SUB>·2CaS products of the reaction of CaS with 12CaO·7Al<SUB>2</SUB>O<SUB>3</SUB> at 1349(±21)K. The sulfur phases crystallized first and the rest of the melt followed the well known CaO-Al<SUB>2</SUB>O<SUB>3</SUB>-SiO<SUB>2</SUB> phase diagram. For comparison, typical ironmaking and steelmaking slags (CaO-Al<SUB>2</SUB>O<SUB>3</SUB>-SiO<SUB>2</SUB>=48-12-40 wt%) were also utilized to study the incorporation of sulfur in their structure. The resulting phases were all glasses with some non-stoichiometry.
